Time to change！
What’s it mean, in English, when native speakers use the word “change” by itself?
当英语母语者在单独使用“change”的时候，到底是什么意思呢？
Let’s take, for example, “It’s time to change.” Change what?
我们来看一个例子，“是时候要做出改变了。” 那么到底要改变什么呢？
We all know the meaning of change by now. It’s to make or become different (改变), or to replace or exchange (交换).

我们都知道“change”的意思。使事物变得不一样，或者替代，交换的意思。
But in this simple phrase, “You need to change,” for example, it’s not very clear. I could mean to change my mind, change my seat, change my position, change my behavior, change my underwear, change money, change buses, change history, and so on.
但是，以“你需要做出改变”这个简单地句子为例，表达的意思并没有很明确。可以指改变主意，交换位置，改变姿势，改变我的行为，把我的内裤换掉，兑换货币，换乘公交，改变历史... 等等。
